To all whom t may concern: i

Beit known that 1, GEORGES ARTHUR DUTRESNE, a subject` of the King ofGreat Britain, residing at Trois Rivieres, vin the Province vof -Quebec,Canada, have invented certain new; and useful Improvements inResilientWheels; and I do hereby declare i that the following is a full,clear, and

exact-description of the invention, such as' will enable others skilledin the art to which it appertains to make andvuse the same.

The present invention relates to new and useful improvements inresilient wheels."l

The primary object of the invention is the provision of a `lresilientwheel so arranged that the outer rim will be yieldingly connected tothe'hub in order to permit the use .of solid tires' with ftheelimination of the `usual shock'to vthe vehicle when such solid tiresare employed. p Another obj ect of the invention is the provision `ofa'resilient'wheel so arranged as to permitof the elimination of the useof cus'- tomary resilient tires and'affording a spring connection whichwill Offer all ofthe desired resiliency required in `wheels of thischar-` acter. ,4 1 Y 4 Y Another object ofthe linvention is theprovisionof awheel'including a hub with an inner rim secured rigidlythereto and an 4 outer rim spaced from the inner rim` and resilientlyconnected thereto, whereby suiiicient resiliency will be provided, thusper-y mitting the elimination of the usual matic tires. 1

A still further objecty of the invention is the provision of a resilientwheel suchv as above referred to which will be, comparatively simple andinexpensive to manufacture, reliable and efficient in use, and readilyoperated. v

With ythe above and other Objects in view, the present invention residesin the novel features of construction, formation, combination andarrangement of parts to be hereinafter more fully described, claimed andillustratedin the accompanying drawing forming a part of the presentapplication; and in which- Figure 1 is a side view of a wheelconstructed in accordance with the present invention;

' Referring now to the accompanying-drawing by corresponding charactersof refer? ence throughout the several views, the numeral 5l designatesin general ymy improved wheel, which comprises a hub portion 6` which isrigidly, secured tothe rim by means of spokes 7 and an inner rim 8 whichis formed concentrically with the said hubpor-v Y A 65,

A plurality of equi-spaced guide members 13 are rigidly securedaboutfthe inner surface of the rim `9 and are formed'withfnarrow-top'longitudinally extendingv channels cross-section and have convex walls.These heads 15 are carried upon the outer face of vor .grooves'ltslidably receiving therein lat- Verally, disposed Aheads 15 which, as,willjbe apparent from Figure 2, are circular kins()v y connecting rods18 which, as indicatedby Figure, have right angularly disposed portionslfformed thereon, and vupon thel free A "ends of said :portionsl theheadsl are.

arranged. The inner or remaining ends of the connecting rods 18 arevpivoted, as at 19, to the inner rim 8, the pivot pins serving to supportrocker arms 20 which are secured to the rods 18. The rocker arms areloosely vand pivotally connected with the opposite endsof links 21.These links'21'arev disposed diametrically of the inner rim and atcertain of their'ends are pivoted to the adjacent ends of the rockerarms, while at their opposite ends they are slotted, vas at 22,'andloosely and pivotally connected to the adjacent ends of thediametrically opposite rockers 20. The connections of the links 21 withthe rocker arms occur directly ad- `jacent the inner ends of the springs11 and thus, it will be understood that stress upon t the wheel will bedirected tov and absorbed by the diametrically arranged pairs of springsl1 through their respective connectinolinks 21; i

' eferring to Figure 1l for the operation y of the device, let it beassumed thatfa stress upon the wheel is exerted atl the lowermostportion thereof. The lowermost springs 11 will tend to compress,vwhereupon the entire inner rim 8 is'torced upwardly, the upper mosthead 15 being guided in the rigid channel member 13. This upwardmovement ot the rim causes a turning of the side rocker arms 20 abouttheir respective pivot points, since the side rods 1S cannot turnbecause or' their retention in the guide members. Each rocker arm endtransmits movement in the opposite directionto the diametricallyopposite rocker arm end, by means of the respective links 21. it willthus be seen that a shock received at the lower portion of the wheelrisiirst transmitted to the upper part, as the consequence of which theside rocker arms are actuated'and divide their resultant motion betweenthem. In this manner, vibration throughout the wheel structure will bereducedy to a minimum, and only those diametrically arranged springs 11in the direct path of stress applied to the wheel from its treadportionwill be aected.

y From the foregoing description taken in connection with theaccompanying drawing it will be manifest that a resilient wheelisfprovided which will ulill all of the necessary requirements of such adevice and it should be further understood in this connectionithatvarious minor changes in the specic detaiis of construction can beresorted to within the scope o the appended claims, without departingfrom the spirit or sacrificing any of the advantages of the in- .ventionHaving thus fully described the invention, what I claim as new anddesire to secure by Letters Patent is:

v1. The herein described resilient wheel comprising an inner and anouter rim,

springs connecting the inner rim and the outer' rim, bars having headsextending from the inner rim and pivotally connected thereto, guidescarried by the outer rim tor receiving the heads ot the bars, rockerarms carried by the bars, and links connecting the rocker arms uponopposite sides of the inner rim, one end of each of said links beingslotted, substantially as and for the purposes set forth. f

2. The herein described resilient wheel, comprising an inner and anouter rim., a hub formed upon the inner rim, a tire carried by the outerrim, springs connecting said rims, bars pivoted to the inner rim andextending outwardly therefrom, guides se cured to the outer rim, saidguides having channels formed therein, heads formed upon the barsslidable within the channels, rocker arms upon the inner ends of saidbars, and links connecting the rocker arms upon opposite sides or' theinner rim, substantially as and t'or the purposes set iorth.

3. The hereindescribed resilient wheel comprising an inner and an outerrim, springs connecting the inner rim and the outer rim, bars extendingfrom the inner rim and pivotally connected thereto, guides carried bythe outer rim for receiving the bars, rocker arms carried bythe bars andlinks connecting the rocker arms upon opposite sides or' the inner rim,said links er;- tending diametrically across said inner rim,

substantially as and for the purposes setv .C L iorth.

in witness whereof I have hereunto set my hand.

GEORGES ARTHUR DUFRES-NE.
